Khapra beetle (Trogoderma granarium) is designated as a quarantine insect pest worldwide due to its voracious feeding on stored grains. Development of insecticidal resistance and its ability to withstand starvation for longer time makes it one of the most destructive arthropod for stored products. It is primarily known as pest of stored wheat, where it can cause up to 30% postharvest losses. During recent years (2010-2014), the reports of occurrence of Khapra beetle in rice supply chains of Pakistan and stiff competition in world rice market resulted in decline of rice exports from 42 million tons to 37 million tons to partner countries and caused 1000 million dollars value loss to rice industry. This review briefly describes the current status and economic impact of Khapra beetle under storage conditions with special focus on its effects on rice supply chain in Pakistan. Potential management practices to regulate population of this arthropod under storage conditions are also given.
